Background:  Provoked vestibulodynia is difficult to treat. The beneficial effects of botulinum toxin are being considered due to the muscular anomalies observed in this pathology. Objective:  We aim to evaluate the efficacy of botulinum toxin A in the treatment of provoked vestibulodynia. Methods:  Patients aged between 18 and 60 presenting with provoked vestibulodynia (according to the 2003 ISSVD classification) received 50 units of botulinum toxin A bilaterally in the bulbospongiosus muscle under electromyographic monitoring. Pain was evaluated by a visual analogue scale, quality of life was evaluated by the Dermatology Life Quality Index and sexual function by the Female Sexual Function Index. Results:  Twenty patients received the injections. Sixteen patients presented with a muscular hyperactivity on the electromyogram. After 3 months, 80% patients improved in terms of pain. Mean VAS values significantly decreased from 8.37 ± 0.95, (extreme values: 4.5-10) to 2.57 ± 2.17 (0-9; p<0.0001) at month 3 and to 3.90 ± 3.01 (0-9; p<0.001) at month 6. Quality of life and sexual function improved significantly during the first 6 months (p<0.0001). After 3 months, 15 patients (72%) were able to have sexual intercourse. Conclusion:  BTA seems to be an effective and safe treatment for treating PV because 100 U botulinum toxin A significantly reduced pain 3 and 6 months after injections without side effects. The treatment improved also quality of life and sexual function of patients. BTA appears to be a promising option for managing sexual pain disorder.
